Zoho Analytics -
This might be a complex question, but I it's in high need in Zoho Analytics. 
Like here while comparing data orange bar is showing last week count and gray bar is showing data before it count.
I would like a chart that can compare data with the following date ranges. This last week (meaning data of last 7 days ) vs. data before last week ( means data range before previous 7 days or we can see we are comparing our last 7 days data from the previous data ).
